Application filed September 11, 1911. Eel-1211mm $8,787.

To all 'IIIIIOWL it may concern Be it known that ll, CHARLEs D. Molin- THUR, a citizen of the United States, residing at. Pittsburgh, in the county of Alli) gheny end State of Pennsylvania, have invented certain new and useful Improvements in Paving-Forms, of which the fol lowing is a specification. I

The invention relates to paving forms and particularly to those adopted for use in the formation of curbs, gutters and side walks. The invention hes-for its objects; the provision of an improved form of mold of simplified construction which may be constructed at a. minimum cost and may be as sembled and disassembled with convenience and rapidity. (lire embodiment of the invention is illustrated in the drawings, wherein:

Figure 1 is a perspective view showing both the sidewalk and curb and gutter forms; Fig. 2 is a side elevation of one of the side sections employed in the mold; Fig. 3 is a plan View of a portion of the/side sec tion; Fig. 4 is an end view of the side sec tion; and Figs. and 6 are side-elevations the spacing plates employed with the sidewalk and curb and gutter forms respectively.

Referring first to the sidewalk form, 1 and 2 are the side sections, preferably channel bars; and 3 3 are whet may be termed spacing plates, such spacing plates being placed at suitable intervals along thelength of the side sections, and secured to such side sections in the manner to be hereinafter de scribed.

As indicoted in Fig. 5, each spacing plots 3 is provided at each end with e lug or our d having i perforation 5 therethrcugh; The

end edges of the side plates 3 abut against the inner feces of the side sections 1 and 2, while the upper portions ofthe webs of the sections and their flanges ere slotted at Bto receive the ears or lugs 4, so that the specing plates may be positioned or removed by s vertical movement. Wedges 6 (Fig. 1) extend through the perforations 5 in the lugs fl efterthe spacing plates have been po sitioned, such wedges 6 lying beneetl'i the flanges of the channel bars 1 and 2,-so that the spacing plates are not only securely locked against endwise movement, but are also held against vertical movement. Where accompanying I lowing 2 the side members 1 and 2 are made up Patented June 8, 1%115.

of more than one section placed endto end, i such sections are secured'together in the -menner indicated in Figs. 2cm 4, the op-r posing sections being provided with straps 7 s whose ends 'sre turned at right angles to the side members as indicated at 8, and area slotted to receive bolts In order to brace the spmc'ing pletes Q end 3 against tilting movement, the rivets IQ and ll are provided (Fig 1, 2 and 3) with their heads spaced apart sufficiently tov receive the edge of the spacing plate simple and inexpensive means 1s thus pros vided for securely maintaining" the spacing plates against lateral or tilting movement. The close spacing of theslots 3' permits of the adjustment of the plates 3.

The curb and gutter form indicated in.

Figs. 1 and 6 is quite similar in construction to the sidewalk form just described. The inner side section however, is made up of two channel bnrsr12 and 13 the position indicated in side member to the side sections or members 1 and 2 heretofore described in connection with the sidewalk form. vThe wood member 15 serves to form the outer face of the curb, such member 15 being held inposition with respect to theside sections 12 and 14 by means of suitable supporting braces or brackets (not shown). Transverse spacing plates 15 are provided at intervals, lugs or cars 16 corresponding to the lugs or core 41 in the sidewalk form. It will be bolted together in Fig. 1. The outer 14 corresponds in all respects such plates being provided withseen thet in both constructions the spacing plates serve to maintain the side members or sections rigidly in their proper positions, and that after the concrete has set the specing plates may be re cdily removed, while the side sections are left in position, or vice verse! v Having; thus, described my inventi on and illustratedits use, whet I claim es new and desire to secure by,- Letters Patent is the fol- L l n combinetion in n paying form, a

lOIlgllllltlillllllV extending member and enopposing ltmfiljliidlllnlly extending member comprising two channel irons with their ends spaced apart and their flanges turned outwardly, means for detachebly securing the two adjacent ends 01. the channels to-- gather, a, verzicaily mo'mble spacjng plate between the, twm members and havmg a perfOlIltGd lug gortloa fit ting between-the said adjacent ends of the channel, and a removable holding member extepding through the perforation in the lug portiml and lying be- 116M311 the upper flanges of me channels.
